The PCB on the computer consists of a motherboard, a hard disk, a memory module, a graphics card, and the like. The plane of the computer motherboard is a PCB (printed circuit board), generally four or six layers. Relatively speaking, in order to save costs, the low-end motherboards are mostly four-layer boards: the main signal layer, the ground layer, the power layer, and the sub-signal layer, while the six-layer board adds the auxiliary power layer and the middle signal layer. Therefore, the six-layer PCB The motherboard is more resistant to electromagnetic interference and the motherboard is more stable. You won't find electronics PCBs today only in computers - although laptops, smartphones, desktops and tablets certainly can't function without quality printed circuit boards, and printed circuit boards for computers make up a large part of the industry. Instead, you'll find machines containing printed circuit boards almost everywhere you look. Your televisio


The aerospace industry requires printed circuits with high reliability in extreme conditions. Any electronic product used for flight or combat must be robust, reliable and compact. Aerospace-related electronic equipment typically requires a 50-year lifespan and needs to be able to operate well for decades. Some of the beneficial properties of ceramic materials for aerospace pcb  electronics include: Thermal expansion coefficient - very close to silicon, much lower than most common metals. Excellent electrical isolation - long life even at long temperatures. Good thermal conductivity as an insulator - good for heat diffusion. Stable dielectric properties and low loss at high frequencies. High chemical stability relative to many chemicals, moisture, solvents and consumables. The aging of the material is very slow due to the consistency. Compatibility with precious metal paste sintering technology - resulting in highly reliable conductors. High processing temperature

Role of auxiliary components in hard gold plating PCB plating solution

Electroplating can be divided into hard gold and soft gold. Hard gold electroplating is an alloy, so its hardness is relatively hard. It is suitable for use in places requiring force and friction. It is generally used as the edge contact point of PCB (commonly known as golden finger). Soft gold, On the other hand, is commonly used to connect aluminum wires On the COB (Chip On Board) or On the touch surface of mobile phone keys, and more recently, it is widely used On both sides of BGA boards. The distinction of hard gold and soft gold, it is the component of this layer of gold that goes up finally plating, when gold-plating can choose electroplate pure gold or alloy, because the hardness of pure gold is softer, so also call "soft gold". Function of auxiliary components in hard gold plating solution    : Boric acid ACTS: as a buffer, which can maintain a relatively balanced PH value of hard gold-plated PCB plating solution with a concentration of 35~55g/l; Nickel ch
